Amiga CD32 full support in the future ?

[dj-nest]

Hi i use the blueretro on Amiga computers and via the parallel mode (PARALLEL_2P_PP) we use the 2 button mode used by Master System. I saw on menu on andvanced settings the CD32 mode and also if i use Auto in Global Config/System settings i got a wrong signal with mouse readings on both joystick ports on amiga.
I assume the adapter i use is using the Master system mode and mode PARALLEL_2P_PP and supports DPAD and 2 button function.

My Questions are:

1. Is there any schematics for CD32 joypad support ? CD32 has a DPAD , 4 buttons , 1 start button and L R flaps

2. Does it need another shematic to be build specific for CD32 support? Searched on github and didnt find anything.

3. Maybe a modified SNES mode would work with the CD32 mode ? On FW files i use the HW1 universal.bin to flash my blue retro.
   SNES mode is very simillar on button quantity and maybe i can help to test it if you can build a specific driver i would gladly help
   with testing it if you like.

Thanks in Advance

CD32 is on my TODO list still. It has not been implemented yet.

Thanks for your fast reply Jacques.
Sweet. I assume it can work in 1P mode to support the 12 button functions.
If you need any help for testing count me in
Just DM me and i will gladly help.

There is an open source CD32 joypad (74LS165N shift register) implementation for the Arduino / ATmega328P available here for inspiration

https://github.com/SukkoPera/OpenPSX2AmigaPadAdapter

From what I can tell the computer signals to the joypad that it wants to switch to CD32 Joypad mode using pin 5 MODE.

It then clocks the button data out of the CD32 pad on pin 6 DATA using Pin 7 CLK which is changed to an output

There is a test program for the Amiga here
